jersey框架 搭建

1、首先加载相关jar包

<dependencies>
		<dependency>
			<groupId>asm</groupId>
			<artifactId>asm</artifactId>
			<version>3.3.1</version>
		</dependency>
		<dependency>
			<groupId>com.sun.jersey</groupId>
			<artifactId>jersey-atom</artifactId>
			<version>1.19</version>
		</dependency>
		<dependency>
			<groupId>com.sun.jersey</groupId>
			<artifactId>jersey-core</artifactId>
			<version>1.19</version>
		</dependency>
		<dependency>
			<groupId>com.sun.jersey</groupId>
			<artifactId>jersey-fastinfoset</artifactId>
			<version>1.19</version>
		</dependency>
		<dependency>
			<groupId>com.sun.jersey</groupId>
			<artifactId>jersey-json</artifactId>
			<version>1.19</version>
		</dependency>
		<dependency>
			<groupId>com.sun.jersey.contribs</groupId>
			<artifactId>jersey-multipart</artifactId>
			<version>1.19</version>
		</dependency>
		<dependency>
			<groupId>com.sun.jersey</groupId>
			<artifactId>jersey-server</artifactId>
			<version>1.19</version>
		</dependency>

	</dependencies>

2、配置web.xml

<servlet>
		<description>JAX-RS Tools Generated - Do not modify</description>
		<servlet-name>JAX-RS Servlet</servlet-name>
		<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer
		</servlet-class>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>JAX-RS Servlet</servlet-name>
		<url-pattern>/mapi/*</url-pattern>
	</servlet-mapping>

通过配置我们知道url访问地址为项目名称+mapi/

3、编写资源访问，在jersey 中所有被访问的都可以被视为资源。

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

@Path("/index")
public class helloController {
	@GET
	@Path("/hello")
	@Produces(MediaType.TEXT_PLAIN)
	public String getUserText() {
		return "Hello,World!";
	}
	
}

就是如此，简单的框架搭建好了，记住这个是无状态的！
